    摘要： The present invention is directed to methods comprising the use of hydroxyapatite chromatography to separate a bispecific antibody from a solution that also comprises one or more byproducts specific to bispecific antibody production. Byproducts specific to the production of bispecific antibodies (bispecific antibody specific byproducts, “BASB”) include fragments of the bispecific antibody and heavier molecular weight variants of the antibody, wherein the fragment and/or variant comprises an Fc domain but does not exhibit affinity for the two different epitopes and/or antigens as exhibited by the desired bispecific antibody. Thus, the methods of the present invention comprise the separation of a bispecific antibody from one or more of its BASB. The hydroxyapatite chromatography methods of the invention may be used alone or may be further combined with standard purification processes and unit operations as is known in the art to achieve any level of purity of bispecific antibody necessary, e.g., for therapeutic and/or diagnostic applications.

    摘要： The current invention reports a method for the purification of a not-glycosylated, heterologous polypeptide, which has been recombinantly produced in a prokaryotic cell, wherein the method comprises three chromatography steps of which the first chromatography step selected from i) hydrophobic charge induction chromatography, or ii) hydrophobic interaction chromatography, or iii) affinity chromatography, or iv) ion exchange chromatography, the second chromatography step is selected from i) anion exchange chromatography, or ii) cation exchange chromatography, or iii) hydroxylapatite chromatography, or iv) hydrophobic interaction chromatography, and the a third chromatography step is selected from i) hydrophobic charge induction chromatography, or ii) anion exchange chromatography, or iii) cation exchange chromatography, or iv) hydrophobic interaction chromatography, whereby the first chromatography step is an affinity chromatography in case of polypeptides capable of interacting with metal ligands, the second chromatography step is not a hydroxylapatite chromatography step in case of polypeptides with an isoelectric point below 6.0, and the third chromatography step can be performed in flow-through mode with polypeptides having a low or high isoelectric point.

    摘要： The current invention reports a method for purifying an immunoglobulin, wherein the method comprises applying an aqueous, buffered solution comprising an immunoglobulin in monomeric, in aggregated, and in fragmented form to an anion exchange chromatography material under conditions whereby the immunoglobulin in monomeric form does not bind to the anion exchange material, and recovering the immunoglobulin in monomeric form in the flow-through from the anion exchange chromatography material, whereby the buffered aqueous solution has a pH value of from 8.0 to 8.5. In one embodiment the anion exchange chromatography material is a membrane anion exchange chromatography material.
